SRS TESTA-DV-SX

The SRS TESTA-DV-SX functions as a dummy-load and diagnostic diagnostic station for direct voltage hoist controllers. In entertainment rigging, direct voltage hoists rely heavily on correct phase orientation and presence to ensure hoist motors turn in the desired direction without damaging the internal hardware.Instead of hooking up a heavy chain hoist to verify a rack, technicians plug the controller or breakout multi-cable directly into the TESTA-DV-SX. The tester systematically reads the three-phase incoming lines from the controller to confirm that power is being delivered smoothly and that the electrical phases follow the right rotational sequence. Its reliance on industry-standard Socapex 19-pin connections simplifies testing by matching the exact loom and fanout infrastructure used on the road.
